Jordy Zomer and Alexandra Sandulescu discovered that the Linux kernel did not properly implement speculative execution barriers in usercopy functions in certain situations. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2023-0459)
Xingyuan Mo discovered that the x86 KVM implementation in the Linux kernel did not properly initialize some data structures. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2023-1513)
It was discovered that a use-after-free vulnerability existed in the iSCSI TCP implementation in the Linux kernel. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2023-2162)
It was discovered that the NET/ROM protocol implementation in the Linux kernel contained a race condition in some situations, leading to a use- after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-32269)
Duoming Zhou discovered that a race condition existed in the infrared receiver/transceiver driver in the Linux kernel, leading to a use-after- free vulnerability. A privileged attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-1118)
